ATTACHMENT FOR GRAIN-SEPARATORS.

SEECFCATION forming part of Letters Patent No. 772,312, dated October 11, 1904.

Application filed November 10, 1902. Serial No. 130,695. (No model.)

To (7,7/7, whom, it nuty concern:

Be it known that vI, JAMES FERNAN, a resident of Huron, in the county of Beadle, in the State oi' South Dakota, have invented an Improvement in Machines Commonly Called Grain-Separators', which improvement is an attachment to the upper end of the grain- .elevator to conduct the grain from said point to the cylinder, substituting the commonlycalled spout, of which the following is a specification.

My invention relates to grain-separators, and particularly to the grain-delivery mechanism, and has special reference to a spiral conveyer connected with the end of the usual conveyer.

The object of my invention is to provide a conveyer which can be adjusted so as to regulate the volume of grain to be separated and prevent the scattering and loss of grain in transit.

In the drawings forming a part of the speciiication, and inrwhich like numerals indicate parts in both views, Figure 1 is a top plan View of the thresher, showing my conveyer mounted within a casing thereon, the top of the same being thrown open. The casing of the endless conveyer, situated at substantially right angles to my attachment and forming a partthereoi', is broken away, exposing the interior oi' the same and its relation to my invention. Fig. 2 is a side elevation showing vthe spiral conveyer forming a part of my invention and a broken-away portion indicating the arrangement of the conveyer within the cylinder. A front elevation of the endless conveyer is also shown, disclosing the means by which it is attached to the separator and thresher-casing. A portion of the top of the conveyer is broken away, showing the endless belt and means for operating the conveyers.

Referring to the drawings, in Fig. 1, 1 represents the top of the thresher-frame, and 2 2l beams extending vertically across the top of the same, being supported thereon by two horizontal wooden bars 3 3', suitably secured to the said casing and forming a walled casing 4, provided with a hinged cover 5. Seated within the casing 4 and adapted for rotation therein is the spiral conveyer 5', rigidly mounted on shaft 6, journaled at one end in the bar-3, and extends out through the casing 4.

The beams 2 2' extend out beyond'th'e frame 1, and to the said extending .portions is secured the endless conveyer 7 by means of `angle-irons 8.

The spiral conveyer 5 rotates within a cyl- .spiral conveyer, extends on an angular plane from the lower part of the thresher, being provided with an endless belt 12, adapted to ride on the cylinder 13, mounted on a short shaft 14, secured in bearings 15, provided on theouter sides of the upper end of the conveyer 7. The said shaft 14 extends out of the conveyer 7, and a gear-wheel 16 and beltwheel 17 are rigidly mounted thereon.

A gear-wheel 18 is mounted on the extended end of the conveyer-shaft 6, and a chain 19 connects the said gear-wheel 16 with the gearwheel18, arranged above and in alinement therewith. i Power applied to the belt-wheel 17 will be transmitted to the connected gears 16 and 18, insuring an even rate of speed for both conveyers. Aplate 19 is slidably mounted on the shaft 6 within the casing 4and regulates the amount of grain to be fed in the conveyer, being operated by adjusting the disk backward or forward from the end of the spiral conveyer 5'.

An opening is provided in the bottomof the conveyer 7, and the projecting portion of the tube 9 ts therein. The grain is fed into thev Ioo the spiral conveyer will be transmitted through the same to the endless conveyer at right angles thereto and from thence to the interior of the thresher. The grain thus in transit is protected from scattering. Then, too, the eonveyers are operated at a uniform speed and under one operation, the amount of grain being regulated to overcome the jamming and collecting' of grain Within the oonveyers.

What I claim, and desire to secure by Letters Patent, is as follows:

l. In a grain-separator, the combination Witha casing, of a cylindrical tube secured therein, and extending Without the said casing, a spiral conveyer revolubly mounted therein, an endless conveyer arranged at right angles thereto, the under face of the upper end of said endless conveyer provided with a vertical opening to receive the extended end of the cylindrical tube and means for securing the same in position.

2. In a grain-separator, the combination With a casing, of a plurality of beams forming a part thereof, a cylindrical tube arranged therein, a shaft extending the length of the said casing, and a spiral conveyer mounted thereon, and extending from a point nearly central to the separator-frame, to the outlying' ends of the said beams, an endless conveyer secured to the top edges of said outlying beam end, a curved metal su pport extending around the periphery of the said cylinder, for holding the same flush With the opening provided on the under face of the upper end of said endless conveyer, and means for securing the said support to the said under faces of the projecting ends of said beams.

3. In a grain-separator, the combination with a casing` of a spiral conveyer mounted on a shaft journale-d therein, a gear-Wheel mounted on one end thereof, an endless conveyer arranged at right angles to said spiral .conveyer, a cylinder mounted on a shaft in the upper end of said endless conveyer, an endless belt arranged thereon, a gear-Wheel and a power-Wheel mounted on the extended portion of said shaft, and a chain connecting the gear-Wheel for transmitting motion applied to said power-Wheel.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

JAMES FERNAN.
